OpenAI began retiring ChatGPT group chats on 9 July 2026, so you can no longer start or join one. Convaa is the same idea, built to stay: one thread, everybody in it, the AI reading the whole conversation as it goes.
| Convaa | ChatGPT group chats | |
|---|---|---|
| Can you still start one | Yes. Make a thread, send the link, people are in it. | No. OpenAI stopped new group chats on 9 July 2026; existing ones became read-only. |
| How people join | A link. Anyone can open it and start prompting without making an account first. | An invite link, but every participant needed a ChatGPT account. |
| Group size | Invite the people who need to be there. Viewers and commenters are free, so the cost of one more is nothing. | Up to 20 people per group chat. |
| Shared context | Everyone prompts the same conversation and the model reads all of it. | The same idea, while it lasted. |
| Models | Claude, GPT and open models, plus a Council that asks several at once and synthesizes. | OpenAI models only. |
| When the chat is not enough | Comments, pins, revision history, action items, document export and an audit trail. | Not offered. |
| Running it yourself | Self-hosted and on-premise deployment available. | Not offered. |
